Application filed May 31,

To all whom it may concern:

Be it known that I, EARL B. SoARsDALn, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented new and useful Improvements in Babbitting Devices, of which the following is a specification.

This invention relates to babbitting devices, and more particularly to a device for babbitting the shoes of locomotive crossheads.

One of the main objects of the invention is to provide a device of the character stated of simple construction and operation by r means of which a cross-head shoe may be completely babbitted at a single operation, and the thickness of the Babbitt-metal at the sides of the shoe may be varied to suit circumstances. A further object is to provide a device which may be readily adjusted to accommodate shoes of different dimensions. Further objects will appear from the detailed description.

In the drawings Figure 1 is atop plan view of a device constructedin accordance with my invention as applied.

Fig. 2 is a side view.

1 Fig. 3 is a section taken substantially on line 33 of Fig. 1.

The device comprises two side rails 1 each provided with a longitudinal slot 2, these slots receiving the end portions of transversel extending bars 3 through which are threac ed adjusting screws 4. Screws 4 are provided at their upper ends with studs 5 which fit into corresponding recesses in .U- frames 6, and with annular shoulders 7 which positively prevent downward movement of, and support the frames 6. Each frame 6 has its end arm bifurcated to receive the end of a securing rod 8, the ends of this rod being secured in arms 6 of frame 6 by a bolt or pin 9, or in any other suitable or preferred manner.

The rails 1 are adapted to receive between them a projection or block a on the underface of a cross-head shoe 6, this shoe being provided with lateral shoulders c which rest upon the upper edges of rails 1. In practice, the shoe is placed upon the rail, after which bars 3 are adjusted in slots 2 so as to bring the U-frames 6 into contact with each end of the shoe. These frames 6 are then adjusted vertically by means of screws 4 so that the upper face of the bight portion Specification of Letters Patent.

of each frame is positioned above the up per face of the body of the shoe a distance corresponding to the thickness of the layer of Babbitt-metal which it is desired to form within the shoe. After this has been. done two blocks 10 provided in their inner edges with grooves cooperating to form vertical holes 11, are placed upon the upper faces of frames 6, and wedges 12 are placed with their inclined faces against the outer sides of these blocks. The wedges and the blocks are then adjusted by means of set screws 13 threaded through arm 6 of frames 6 so as to center the blocks and wedges transversely of shoe 5. The wedges are driven into position after the blocks 10 and the wedges have been centered by means of screws 13, these wedges serving to effect a final adjustment and to secure the wedges and blocks in position. As will be understood, the wedges and blocks may be readily adjusted so as to be positioned closer to one flange of the shoe 2) than to the other so as to correct any inaccuracies in the shoe or in the cross-head frame upon which the shoe slides. After the device has been set as de* scribed, the molten Babbitt'metal is poured into the spaces 1 1 between the outer faces of wedges 12 and the flanges of shoe .7) so as to form a coating or lining for the inner faces of the flanges. A portion of this metal will also flow beneath wedges 12 and blocks 10 so as to assist in forming a covering for the upper face of the block. To insure the completion of the covering for the upper face of the block, the metal may also be poured through the central opening 11, as considered in Fig. 1. During this operation the ends of the spaces 14: may be closed by plates temporarily inserted between the ends of the shoe and arms 6 of frames 6, as will be understood.

/Vhat I claim is 1. In a device of the character described, supporting rails, bars mounted on said rails and adjustable longitudinally thereof, frames, means for supporting said frames and for adjusting the same toward and away from the bars, and means carried by the frames and adapted to be positioned within a cross-head shoe so as to form with the walls thereof spaces for reception of Babbitt-metal.

2. In a device of the character described, rails each provided with a longitudinally extending slot, cross-bars extending through said slots, frames adapted for reception of means for forming; with the walls of a crosshead' spaces for receiving Babbitt metal, and means for supporting said frames and "for adjusting the same toward and away from the cross-bars. r

3. In a device of the character described, rails cross-bars adjustable longitudinally of the rails, frames, means carried by said frames and adapted to be nositionedwithin a cross-headshoe and to m with the walls thereof spaces for re ion of Babbittmetal, means for adju the first mentioned means in said i.

nes transversely thereof, and means for supporting said frames and for adjusting the same toward and away from the rails.

4. ln a device of the character described, rails, cross-bars adjustable longitudinally of said rails, frames of substantially U-shape, means carried by said frames and adapted to be positioned within a cross-head so as to form wlth the walls thereof spaces for reto adjust the framestoward and away from l said bars.

in testimony whereof I aiiix my signature.
